Answer:. d. Last year some of their freshman students had a score of at least 1120 on the exam.
Step-by-step explanation:
If the average score is 1120, then some students scored more than 1120. Hence, those students scored at least 1120
(4b+3) (2b−5)
(4b+3) (2b+−5)
(4b) (2b) + (4b) (−5) +(3) (2b) +(3) (−5)
8b²−20b+6b−15.
= 8b²−14b−15.
Hey there!
Set up an equation. This would be 4+0.5x=12. You have to get x by itself, so subtract 4 on each side. You get 0.5x=8. Divide by 0.5 on each side to get x=16. Heidi purchased 16 tickets.
I hope this helps!
Add up all of the side lengths and you get 148.4 as the perimeter.
subtract that from 150 and you're left with 1.6 m left of tape
